Ready in: 35 mins

Ingredients

Serves: 4

• 3 tablespoons olive oil
• 2 onions, thinly sliced
• Salt and pepper
• 1 1/4 pounds flank steak
• 3/4 cup mayonnaise
• 1/4 cup jarred horseradish
• 1 loaf Italian bread, ends trimmed and loaf cut into 8 slices

Preparation method

Prep: 20 mins | Cook: 15 mins

1. Preheat grill to medium-high.

2. Pour 2 tablespoons olive oil into a skillet and set over medium-low heat. Cook onions in hot oil with salt and pepper, stirring, until browned. This will take a good 15 to 20 minutes.

3. Meanwhile, coat steak with 1 tablespoon oil and sprinkle with salt and pepper. Place on grill and cook for 6 minutes, then flip and grill for 6 to 8 more minutes (until beef reaches desired doneness). Transfer to a cutting board.

4. Whisk mayonnaise together with horseradish and salt and pepper to taste in a bowl. Coat bread slices on one side with the mixture.

5. Thinly slice beef. Top 4 of the bread slices with the beef, and onions, then place the rest of the bread slices on top of the fillings. Serve.
